Custom Backend & Data Systems That Replace Your Spreadsheet Mess

One reliable backend for your orders, customers, inventory, and operations — built around how your business actually runs.

The problem

Your business is held together by spreadsheets and copy-paste

"We run our whole business on Excel sheets and copy-paste." Orders live in one sheet, customers in another, payments in a third, and someone on your team is the only person who knows how it all connects. Files break, numbers drift, and every new hire takes a month to learn the workarounds.

One backend, one source of truth

AIERAX builds a custom backend that holds all your business data in one place — orders, customers, stock, invoices, staff actions — with clean APIs so your website, app, and tools all stay in sync. No more conflicting sheets, no more lost records, no more guessing which file is the latest version. You get a system that scales as you grow, instead of breaking under it.

How it works

  1. Map your real workflow

    We sit with you and trace how an order, lead, or job actually moves through your business today — sheets, WhatsApp, emails, the lot. That becomes the blueprint.

  2. Design the data model

    We design a clean database that fits your operations: customers, products, orders, payments, suppliers, staff. Every record has one home and one owner.

  3. Build secure APIs and admin tools

    We build the backend services and APIs your website, app, and automations talk to, plus a simple admin panel your team can actually use without training.

  4. Migrate your existing data

    We import your spreadsheets, old CRMs, or legacy systems into the new backend so you don't lose history or start from zero.

  5. Host, monitor, and support

    We deploy it on reliable cloud infrastructure with backups, monitoring, and ongoing support so you never wake up to a broken system.

A real example

A Chennai-based custom apparel brand was processing around 60 orders a day across Instagram DMs, WhatsApp, and a website, tracking everything in 4 separate Google Sheets. AIERAX built a unified backend with one orders database, inventory sync, and a simple admin dashboard. Order entry time dropped from around 8 minutes per order to under 1 minute, stock mismatches fell to zero, and the owner stopped spending 2 hours every night reconciling sheets.

Common questions

How much does a custom backend cost for a small business?

It depends on how many workflows you want to digitise, but most SMB backends we build land between a focused MVP and a full operations system. We scope it in phases so you get a working core fast and add to it as your business grows, instead of paying for a giant system upfront.

Can you replace our Google Sheets without us losing any data?

Yes. We import every sheet, tab, and historical record into the new database before you go live, and we run both side by side for a short period so your team can verify everything matches. Once you're confident, we switch over.

Do we own the code and data, or are we locked in?

You own all of it — the code, the database, and the infrastructure account. We hand over full access and documentation, so even if you stop working with us, you can hire any developer to take it forward.

How is a custom backend better than just using a CRM or ERP?

Off-the-shelf CRMs and ERPs force your business to fit their model and charge per user forever. A custom backend fits your exact workflow, costs you once to build, and connects directly to your website, WhatsApp, automations, and AI tools without messy integrations.

How long does it take to build?

A focused first version is usually live in 4 to 8 weeks, depending on how many workflows we're replacing. We ship in stages so you see real value early instead of waiting months for a big launch.

Can the backend connect to our existing website and WhatsApp?

Yes. The backend exposes clean APIs so we can plug it into your existing website, mobile app, WhatsApp Business, payment gateways, accounting tools, and any AI automations we build for you.
