Tabby for business: merchant setup, fees & integrations

Review Tabby merchant onboarding, checkout integrations, fees, settlements and refunds, with a practical framework for testing installment payments.

Adding installments can make a purchase easier for a customer. For the merchant, the decision is less about the checkout badge and more about what remains after fees, delivery, returns and the time spent reconciling payouts.

Tabby should be evaluated as a payment method with its own commercial terms and operating workflow. Start with eligibility and a merchant quote, then run a small checkout-to-refund pilot. A higher average order value is useful only if it produces a better business result.

Understand the two different payment timelines

The customer follows the installment arrangement offered at checkout. The merchant receives settlements according to its agreement with Tabby. Those are separate timelines; do not build cash-flow forecasts by assuming the store receives each shopper installment directly.

Tabby's developer introduction describes operations in Saudi Arabia and the UAE. That does not establish merchant onboarding across every GCC country. Confirm the legal entity, activity, sales channel and bank account before allocating implementation time.

The merchant product page is a starting point for the application. Business approval and approval of an individual shopper's purchase are different decisions. Your checkout needs an ordinary alternative when Tabby is unavailable or the customer is not approved.

Get a quote that finance can actually model

Tabby's merchant pricing guidance describes merchant-dependent commission and a fixed transaction fee. It does not supply a universal rate that every store can use. Ask for the written schedule applying to your entity and channel.

Have the quotation answer five practical questions: what percentage and fixed fee apply, how applicable tax is treated, what happens to fees after a full or partial refund, which other deductions can occur, and when funds become payable. If a promotion changes the rate, record its end date and the rate that follows.

Here is an illustrative unit-economics check, not Tabby's quoted pricing.

Line item	Illustrative amount	Decision use
Customer order value	AED 500	Use the post-discount amount on the same tax basis as your costs.
Product cost	AED 350	Shows whether the SKU has room for payment fees.
Delivery and other variable cost	AED 40	AED 30 delivery plus AED 10 other variable cost.
Contribution before payment method	AED 110	Baseline before any provider charge.
Assumed provider charge	AED 25	Replace with the written Tabby quote.
Contribution after assumed charge	AED 85	Returns, advertising and overhead are not included.

Run the same calculation with the real quote and with a returned order. A fee that looks manageable on a high-margin accessory may be unacceptable on a discounted appliance. Use the same tax basis throughout the worksheet so you are not comparing tax-inclusive revenue with tax-exclusive costs.

Install the payment flow and test the whole order

Tabby provides official instructions for Shopify and WooCommerce. Follow the current route linked from those documents rather than an old tutorial or an unrelated plugin with a similar name.

For Shopify, verify the store country, approved merchant account and current payment-app configuration. For WooCommerce, record the WordPress, WooCommerce and plugin versions and test on staging before changing the trading store. Credentials should be managed by an authorized administrator, not copied into a shared task or support conversation.

A product-page installment message is different from a working payment integration. Test the amount displayed after discounts, shipping and any applicable tax. Then verify what the order system records after payment approval, abandonment and rejection.

For a custom integration, agree with the developer which provider event makes an order eligible for fulfillment. Browser redirects and screenshots are not sufficient payment evidence. Ensure repeat notifications cannot create duplicate shipment instructions. These are implementation requirements to validate against the current integration, not a claim that installing any plugin automatically satisfies them.

Reconcile the payout, not just the checkout

Tabby's payout guidance describes flexible and fixed weekly arrangements. Confirm the applicable choice and bank timing in the merchant account. A payout being initiated and funds arriving at the bank are different events.

Create a reconciliation worksheet with the store order ID, Tabby reference, original order value, refunds, fees, adjustments, settlement reference and net bank amount. Finance should be able to move from one bank deposit back to its underlying orders without asking a developer.

Suppose a payout contains 18 orders and one refund from the previous week. Matching the deposit only to this week's sales will create a false discrepancy. Carry the refund reference through to the original order, and keep the provider settlement report with the accounting record.

The business payments setup guide explains why the merchant account, business bank account and accounting workflow need to be planned together.

Decide who owns a return before accepting the first one

Write a short internal procedure for cancellation before dispatch, a full return and a partial return. Specify where staff initiate the action, who approves it and which confirmation establishes that it completed. Check the integration's supported refund route in your merchant setup rather than issuing a separate bank transfer by habit.

A separate transfer can leave the provider's order balance unchanged while the customer believes the purchase has been refunded. If an exception requires an outside payment, finance and support need a documented way to reconcile both sides.

Give support a plain-language response that explains the store's action and directs questions about the shopper's installment account to the correct provider channel. Do not promise that every bank or customer account reflects a refund immediately.

Judge the pilot on contribution and operational effort

Start with a defined product group and record approval rate, checkout completion, order value, returns, net contribution and reconciliation time. Compare similar products and periods. Separate first-time customers from existing customers if the sample allows it, and do not attribute a simultaneous promotion's entire effect to installments.

Decision	Minimum evidence before changing rollout
Choose or expand	Comparable orders show acceptable net contribution after quoted fees, refunds and support effort, and payouts reconcile cleanly.
Keep testing	Checkout completion or order value improves, but returns, failed payments or reconciliation effort are not yet stable.
Pause or skip	The target SKUs lose margin, refunds cannot be processed through the supported route, or finance cannot match settlements to orders.

Keep Tabby if the results justify the real fees and the team can reliably handle exceptions. If you also evaluate Tamara, use the same merchant country, product mix and accounting assumptions. For the underlying storefront, the Shopify versus WooCommerce guide covers the platform decision; a payment-method pilot should not become an accidental platform migration.
