The verdict in three sentences
For a Dubai services company invoicing 400 businesses, a payment gateway connected to invoicing lets you attach a payment link to every invoice and cut days sales outstanding (DSO) by about 20 days. Fees range from near zero to 3.5 % depending on the payment method, and the right choice depends on your customer mix: large accounts by bank transfer, SMEs by card or instant payment, foreign subsidiaries by international card. Integration costs AED 30,000 to 60,000 and ships in 6 weeks, with automatic reconciliation that saves as much as the DSO reduction.
B2B payment methods and their real cost in 2026
The CFO currently collects by cheque, bank transfer and occasionally post-dated cheques, with manual reminders and reconciliation done by hand in Excel. A gateway brings every method behind a single link and a single statement. Here are 2026 orders of magnitude in the UAE.
| Payment method | Indicative fee | Time to settle | Typical B2B use |
|---|---|---|---|
| Local debit and credit card | 2 to 2.5 % | T+2 to T+3 | SMEs, corporate cards |
| International card | 2.9 to 3.5 % | T+3 to T+7 | Subsidiaries and foreign clients |
| Instant payment via Aani | Low fixed fee | Seconds | Local businesses, medium amounts |
| Bank transfer with unique reference | AED 0 to 10 fixed | T+0 to T+1 | Large accounts, large amounts |
| Digital wallets (Apple Pay, Google Pay) | Same as card | T+2 to T+3 | Small amounts, on-the-go approvers |
| Multi-method gateway (one API) | 0 to 3.5 % by method, plus subscription | By method | All, one dashboard |
Two points weigh on the choice. Card fees on a AED 500,000 invoice are prohibitive, so a bank transfer with a unique reference must remain the default for large amounts. And the UAE e-invoicing programme rolling out over 2026 and 2027 argues for an architecture where invoice, payment and accounting entry share the same identifiers from the start.
Integration with invoicing software: what you pay for
A payment link alone is not enough. Time is saved when the invoice, payment and accounting entry match up without human intervention.
| Component | Description | 2026 cost |
|---|---|---|
| Payment link on every invoice | Generated at issue, sent by email and WhatsApp | AED 7,500 to 12,000 |
| Multi-method gateway connection | Card, wallets, Aani, bank transfer | AED 9,000 to 15,000 |
| Automatic reconciliation | Payment received, invoice closed, entry posted | AED 7,500 to 18,000 |
| Automatic reminders | D-3, D+7, D+15 with payment link | AED 3,000 to 7,500 |
| Treasury dashboard | Receivables, DSO, 30-day forecast | AED 3,000 to 7,500 |
| Total project | 6-week timeline | AED 30,000 to 60,000 |
| Operations | Hosting and maintenance | AED 1,800 per month |
The typical plan: 1 week to open merchant accounts and gather documents (trade licence, Emirates ID of the signatory, bank letter), 3 weeks of development and connection to the invoicing software, 1 week of testing with 20 customers, 1 week of rollout. If your software is an off-the-shelf tool without an API, plan an automated export or a move to a more open tool.
Mini case study
Rania, CFO of a services company in Dubai, invoices about AED 9,000,000 a month to 400 businesses, with a DSO of 75 days. Bringing it down to 55 days frees AED 6,000,000 of cash, or about AED 420,000 a year of overdraft avoided at 7 %. Automatic reconciliation saves 60 accountant hours a month at AED 150, or AED 108,000 a year, and reminders reduce bad debt by 0.3 % of revenue, or AED 324,000. On the cost side, 35 % of collections go through the gateway at 0.9 % on average, or AED 340,000 a year. Net gain: about AED 510,000 a year for a AED 45,000 project, paid back in a few months.

FAQ
Should fees be passed on to customers?
In B2B it is rarely well received. Most companies absorb card fees on small invoices and steer large invoices to bank transfer or Aani, which cost a few dirhams at most.
Can a large account pay a AED 1,000,000 invoice by card?
Technically yes, but a 2.5 % fee would cost AED 25,000. For such amounts, the link automatically offers bank transfer with a unique reference, reconciled without intervention.
What documents are needed to open merchant accounts?
Trade licence, Emirates ID and passport of the signatory, and a bank letter. Allow 5 to 15 business days depending on the acquirer, in parallel with development.
Our invoicing software has no API. Is that a blocker?
No. Synchronization by automated export works, for an extra AED 4,500 to 9,000. Beyond 400 customers, moving to open software often pays for itself within a year.
How long before DSO drops?
The first effects appear from the first billing cycle. A drop of 15 to 20 days is common after 3 months, once customers get used to the link.
