Connect your billing in an afternoon
aiever is plug-and-play by design. It does not care what raises your bills. Give your billing system an API key and a URL, and every sale becomes a customer record, a points accrual and a message.
- Secure API-key authentication per integration source
- Bill push, bill reversal and stock-arrival webhooks
- Works with Tally, custom POS software, Shopify, WooCommerce or an in-house ERP
What Billing & POS Integration does
One endpoint to start
POST the bill — mobile, name, amount, line items — to the billing webhook. aiever upserts the customer, records the purchase and queues the post-billing message.
API key per source
Each connected system gets its own key, so you can see exactly which system sent what, and revoke one without disturbing the rest.
Reversals that reverse properly
A cancelled bill must claw back points and reduce the recorded purchase amount. If only the points are removed, tiers and lifetime value quietly drift wrong. aiever does both.
Stock arrival alerts
A separate webhook lets your purchase-order system announce new stock, which aiever turns into a targeted alert to customers who buy that category.
Ecommerce orders too
Online orders post to the order webhook and merge into the same customer identity as counter purchases.
Read the log
Every inbound call is recorded with its payload and result, so a failing integration is diagnosed in minutes rather than argued about for a week.
Setting it up
How it works
- 1
Create an integration source
Name the system and generate its API key in aiever.
- 2
Point it at the webhook
Your billing software posts to /api/v1/webhooks/billing with the key in the header.
- 3
Verify with one bill
Raise a test bill and watch the customer, purchase and points appear.
- 4
Go live
From then on every bill feeds loyalty, segmentation and campaigns automatically.
Billing & POS Integration — questions we get
We use Tally. Is that supported?
Yes. Tally pushes bills to the aiever webhook through a TDL extension. This is running in production for retailers today, including full reversal handling.
What if our POS is custom-built?
That is the normal case. The integration is a single authenticated HTTP POST with a JSON body — any developer can add it in a day.
Do we have to send you our sales data?
You send what marketing needs: mobile, name, bill amount, date and optionally line items. It stays in your own aiever database, on your own instance.
