The B2B Payment Problem
B2B service companies have a cash flow problem that nobody talks about openly. You send an invoice. You wait. Then you wait some more.
Standard B2B payment terms are 30 to 60 days. But the actual time between invoice sent and payment received is closer to 45 to 90 days. That gap is where cash flow goes to die.
The reasons stack up. The invoice arrives in someone's inbox on a Friday afternoon. It sits there. The accounts payable person is on holiday. Then the approver needs to sign off. Then the payment run is next Thursday. Then a bank holiday pushes it another week.
For a recruitment agency placing 20 candidates a month or a marketing agency billing retainers plus project work, that delay means you're funding your clients' working capital. You delivered the service in January. You might see the money in April.
The real cost isn't just the cash flow squeeze. It's the time your team spends chasing. Finance people sending "friendly reminder" emails. Account managers making awkward phone calls to clients they want to keep happy. A mid-market services business can easily burn 15 to 20 hours a month on payment follow-ups.
That's a hidden headcount cost that never shows up on anyone's P&L.
Why Invoices Alone Don't Work
The standard B2B payment process looks like this: you generate an invoice in your accounting software, export it as a PDF, attach it to an email, and send it with "please find attached" in the subject line.
Now look at what your client has to do to pay you.
Open the email. Download the PDF. Note the amount and reference number. Log into their online banking. Add you as a new payee (if they haven't already). Enter your sort code, account number, and payment reference. Get approval from someone with payment authority. Wait for the next payment run.
Every one of those steps is a friction point. Every friction point adds days.
Compare that to how the same person buys something personally. They tap a link, see the amount, tap Apple Pay, done. Sixty seconds. No reference numbers. No bank logins. No approval chains for a subscription renewal.
B2B payments are stuck in 2005. The service has changed, the delivery model has changed, the client relationship has changed. But the payment mechanism is still "PDF attached to an email, please transfer when convenient."
That's why invoice payment terms are a fiction. The terms say 30 days. The process takes 60.
Payment Links: The Fix That Actually Works
A payment link is a URL that opens a branded checkout page. Your client clicks it, sees the amount and description, picks their payment method (card, bank transfer, or digital wallet), and pays. The whole thing takes under 60 seconds.
Instead of attaching a PDF and hoping for the best, you include a "Pay Now" link directly in the invoice email. The client clicks it on their phone between meetings. Payment done.
This isn't a new concept for consumer payments. Every Uber receipt has a payment link. Every SaaS subscription renewal is a link. But B2B service companies have been slow to adopt it because most payment link tools are built for retail and ecommerce, not for service businesses billing clients on account.
What makes a payment link work for B2B is different from retail:
Custom amounts. You're not selling a product at a fixed price. Every invoice is different.
Reference matching. The payment needs to carry your invoice number so you can reconcile it automatically.
Branding. Your client sees your logo and colours on the checkout page, not some third-party payment provider's branding.
Multiple payment methods. Some clients want to pay by card. Others prefer bank transfer. Government clients might require a specific method. The link should support all of them.
PSP flexibility. You might process through Stripe today but want to switch to Worldpay next quarter. Or your client's procurement team mandates a specific provider. Your payment links should work with whatever PSP you or your client needs.
The result: clients pay faster because paying is easy. You spend less time chasing because there's nothing to chase. The link is the nudge and the mechanism in one.
Multi-Channel Collection for B2B
A single payment link in an invoice email is good. A multi-channel collection strategy is better.
Here's what that looks like in practice.
Day 0: Invoice email with payment link. The invoice goes out with a "Pay Now" button. No PDF attachment needed (though you can include one for records). The link is the primary call to action.
Day 7: SMS reminder. A short text message: "Invoice #1247 for £4,200 is due in 23 days. Pay now: [link]." SMS open rates are above 90%. Your client sees this on their phone, taps, pays. No email hunting required.
Day 14: Second reminder. Another SMS or email, depending on the client's preference. The link is the same. The message is slightly more direct.
Day 30: WhatsApp follow-up for key accounts. For your bigger clients, a WhatsApp message from their account manager feels personal without being pushy. "Hi Sarah, just flagging invoice #1247 is due today. Here's the link if it's easier: [link]." It lands differently from a generic accounts receivable email.
Day 45+: Phone follow-up with voice payment. For overdue invoices, your team calls the client. If the client says "I'll pay it now," your team can take the payment right there on the call using PCI-compliant voice payment. No "I'll send you the bank details again" loop. No waiting another two weeks.
This multi-channel approach works because it meets clients where they are. Some people live in their email. Some respond to texts. Some need a phone call. The payment link is the constant. The channel is the variable.
Industry-Specific Payment Patterns
B2B services aren't all the same. The payment challenge varies by sector.
Recruitment Agencies
Recruitment has a unique billing structure. Placement fees are typically 15 to 25% of the candidate's first-year salary, invoiced on start date. That's a large one-off payment, often £8,000 to £25,000, from a client who might only hire through you once or twice a year.
The problem: your client's hiring manager approved the placement but has no authority over payments. The invoice goes to accounts payable, who have never heard of you. The approval chain is long because the amount is high.
Payment links help because they reduce the admin burden on AP. Instead of processing a manual bank transfer, AP clicks a link, pays by card or bank transfer, and the reference matches automatically. For temp billing with weekly or monthly invoices, recurring payment links cut the chasing cycle entirely.
Split billing adds another wrinkle. When a placement fee is split across departments or entities, you can send separate payment links for each portion with the correct reference and amount. No confusion, no partial payments sitting in limbo.
Marketing Agencies
Marketing agencies juggle retainers and project work. The retainer is predictable but still needs collecting. Project milestones are variable and often disputed ("we haven't signed off that deliverable yet").
For retainers, a monthly payment link sent on the same date with the same amount becomes routine. Clients expect it, click it, pay it. It's as close to a direct debit as you can get without the setup hassle.
For project milestones, payment links tied to specific deliverables work well. "Phase 2 website build complete. £12,000 due. [Pay Now]." The link arrives at the moment of delivery, when the value is fresh and the client is most willing to pay.
IT Services and MSPs
IT services companies deal with two payment types: recurring managed service contracts and ad-hoc support tickets. The managed service is straightforward. The ad-hoc work causes payment delays because clients don't expect the invoice and often query it.
Sending a payment link at the point of ticket closure, with the ticket reference in the description, reduces queries. The client sees "Support ticket #4892: server migration, 3.5 hours at £120/hr = £420" and pays immediately. No surprises. No "what was this for?" emails three weeks later.
Facilities Management
Facilities management companies have contract payments (fixed monthly amounts for ongoing maintenance) and call-out charges (variable, often urgent). Contract payments are predictable and suit automated monthly links. Call-out charges are the problem.
A burst pipe at 2am generates a £600 emergency call-out charge. The engineer fixes the problem. The invoice goes out three days later. The client, already annoyed about the burst pipe, puts the invoice at the bottom of the pile.
Sending a payment link by SMS immediately after the job is completed, while the client is still grateful the problem is fixed, dramatically improves collection speed. "Emergency call-out completed. £600 due. [Pay now]." Context and timing do the heavy lifting.
What to Look for in a B2B Payment Collection Tool
Not all payment link tools are built for B2B service companies. Here's what matters.
PSP flexibility. You should be able to use your existing payment provider. If you're processing through Worldpay or Barclaycard, you shouldn't have to switch to Stripe just because your payment link tool only supports Stripe. Look for a tool that works with 40+ PSPs and lets you bring your own gateway.
White-label branding. Your clients should see your logo, your colours, your domain on the checkout page. Third-party branding erodes trust, especially for high-value B2B invoices. If a client is paying £15,000 and the checkout page says "Powered by [some company they've never heard of]," they'll hesitate.
Reference matching and reconciliation. Every payment link should carry a reference (your invoice number) that flows through to your bank statement and accounting software. Manual reconciliation of "mystery payments" kills the efficiency you gained by collecting faster.
Team access and permissions. Your account managers need to create and send payment links. Your finance team needs to see payment status and reporting. Your MD needs a dashboard. Per-user access with role-based permissions matters when you have 10 or 20 people involved in billing.
Multi-channel delivery. Email alone isn't enough. You need SMS, WhatsApp, and the ability to send links during phone calls. The more channels you cover, the faster you collect.
Reporting and audit trail. For every payment link, you should see: when it was sent, when it was opened, when it was paid, which method was used, and who on your team sent it. This data feeds back into your collection strategy.
PCI compliance. You're handling payment data. Your tool needs to be PCI DSS compliant so you don't carry that burden yourself. PCI DSS Level 1 is the highest standard. Anything less is a risk for a service business handling high-value B2B transactions.
How Shuttle Fits
Shuttle's Links Checkout is built for exactly this use case. It connects to 40+ PSPs (bring your existing provider or switch later without changing your payment workflow), supports white-label branding, and delivers payment links across email, SMS, and WhatsApp.
Your team creates payment links from a shared dashboard at $49 per user per month. Each link carries your invoice reference, your branding, and your choice of payment methods. Clients pay on a checkout page that looks like yours, not like a third party's.
For phone follow-ups on overdue invoices, Shuttle's Voice Checkout lets your team take PCI-compliant payments during the call. The client says "I'll pay now" and actually pays now, instead of promising to "sort it this week."
Everything is PCI DSS Level 1 compliant, so your team never sees or handles card data.

FAQ
Do B2B clients prefer to pay by card or bank transfer?
It depends on the amount. For invoices under £1,000, card is common because it's instant and many businesses have company cards. For invoices over £5,000, bank transfer is more typical because card processing fees are a factor and corporate card limits may not cover it. The best approach is to offer both options on every payment link and let the client choose.
What about clients who insist on 60-day payment terms?
Payment links don't change your agreed terms. They change how quickly your client acts once the invoice is due. A client on 60-day terms still has 60 days. But instead of paying on day 85 because the bank transfer was a hassle, they pay on day 60 because clicking a link takes 30 seconds. You can also send the payment link at the start of the term so it's ready when the payment date arrives.
Can payment links integrate with our accounting software?
Yes. Most B2B payment collection tools integrate with Xero, QuickBooks, Sage, and other accounting platforms. The integration typically means that when a payment is made through a link, it's automatically marked as paid in your accounting system with the correct reference. This eliminates the manual reconciliation step.
What if a client disputes the amount?
Payment links for a specific amount actually reduce disputes. The client sees exactly what they're paying and for what before they click "Pay." If there's a query, it happens before payment rather than after. For milestone-based billing, sending the link with a clear description of the deliverable ("Phase 2 website build, as per SOW dated 15 Jan") pre-empts most disputes.
Is it secure enough for high-value B2B transactions?
With a PCI DSS Level 1 certified provider, yes. This is the same security standard used by the largest banks and payment processors. The payment page is hosted on secure infrastructure, card data is encrypted and tokenised, and your business never touches sensitive payment information. For a £20,000 invoice payment, this is actually more secure than a client reading their card number over the phone to your accounts team.
How quickly do we receive the funds?
Settlement times depend on your PSP and the payment method used. Card payments typically settle within 1 to 3 business days. Faster Payments bank transfers in the UK settle the same day or next business day. This is dramatically faster than waiting for a client to initiate a manual bank transfer "sometime this week."
