Purchase
Purchase requests, purchase orders to approved suppliers, goods received notes against each order, and supplier bills matched to what actually arrived.
ERP software
Custom ERP software, built around how you work.
Purchase, stock, sales and accounts in one system, so every team sees the same numbers. We design it around your process, build it, host it and keep it running.
What it covers
Everything a growing business runs on, in one system
Pick the modules you need now and add the rest later. They share one set of items, customers, suppliers and numbers.
Stock and warehouses
Live stock by item, location and batch, transfers between godowns and reorder levels that raise an alert before you run out.
Inventory softwareSales
Quotations, sales orders, delivery challans and invoices, each created from the one before, so nothing is typed twice.
Accounts
Customer and supplier ledgers, receivables and payables, payments received and made, and the reports your accountant asks for.
GST-ready invoicing
Tax invoices with GSTIN, HSN or SAC codes, place of supply and the CGST, SGST or IGST split. For the UAE, VAT invoices with your TRN.
Billing softwareApprovals
Purchase orders, discounts above a limit, credit notes and payments wait for the right person, with a record of who approved what and when.
Workflow softwareProduction
Bills of materials, work orders and the raw material they use, for businesses that make what they sell.
People and payroll
Staff, attendance, leave and payroll come from DueDoor HRMS, connected to the same system.
DueDoor HRMSOne document trail
Every document knows where it came from
In an ERP we build, each document is created from the one before it. Open an invoice and you can walk back to the order, the challan and the stock that left the godown.
Typed once
Items, quantities and prices carry forward from document to document, so the same line is never keyed in twice.
Stock moves with the paperwork
A goods received note adds stock and a delivery challan takes it out, at the right location and batch.
Matched before you pay
A supplier bill is checked against the purchase order and what was received, and differences are flagged.
Approvals in the flow
Documents above your limits stop for approval before they go out, and the approver sees the full trail.
One set of numbers
Sales, purchase and stock reports read from the same records, so teams stop reconciling spreadsheets.
Your rules, not a template
Numbering series, units, price lists, credit limits and roles are set the way you already work.
GST-ready means the invoice carries the fields GST law asks for. We do not claim any government certification for the software, and your CA still reviews and files your returns.
How we build it
How we build your ERP
A first release that removes the most manual work, live on real orders, then module by module.
DueDoor designs, builds, hosts and runs it. One team you can call, from the first sketch to the next new module.
- 01
Map how you work today
We sit with purchase, stores, sales and accounts and write down every document, approval and report you use now, including the Excel sheets.
- 02
Agree the first release
We pick the modules that save the most time first and write them up as screens and rules you can check before we build.
- 03
Build and bring your data in
We build it, then import your items, customers, suppliers, price lists and opening stock from your current files.
- 04
Run it beside the old way
Your team uses it on real orders while the old process still runs, and we fix whatever does not fit.
- 05
Go live, hosted and backed up
We host it on cloud servers we set up and look after, with your data encrypted, backed up every night and monitored.
- 06
Keep adding
New modules, reports and integrations as the business grows, from the same team you already talk to.

FAQ
Questions we get asked
What is included in a custom ERP from DueDoor?
The modules you choose from purchase, stock and warehouses, sales, accounts, GST-ready invoicing, approvals, production and reports, with DueDoor HRMS for staff and payroll. We build the first release around the work that costs you the most time, then add modules as you need them.
Is the ERP GST compliant?
Invoices carry the fields GST law asks for: GSTIN, HSN or SAC codes, place of supply and the CGST, SGST or IGST split. We do not claim any government certification for the software. If your business falls under GST e-invoicing, the system can be connected to the Invoice Registration Portal through an authorised provider so invoices carry an IRN and QR code. Your CA still reviews and files your returns.
Why not use a packaged ERP?
Packaged ERPs work well when your process matches theirs. When it does not, teams end up working around the software in Excel. A custom ERP follows your documents, approvals and reports, and you only get the modules you use.
Can you move our data from Excel or our current software?
Yes. We import items, customers, suppliers, price lists and opening stock from your files or exports, and check the numbers with you before go-live.
Where is the ERP hosted?
On cloud servers we set up and manage for you, with your data encrypted, backed up every night and monitored, so a problem raises an alert before your team notices it.
Does it work for businesses in the UAE?
Yes. For the UAE we build VAT invoices that carry your TRN and VAT at 5% where it applies. Payroll for UAE staff, with end-of-service gratuity and the WPS salary file, comes from DueDoor HRMS.
Can the ERP connect to our online store and payments?
Yes. Shopify orders can come in as sales orders, invoices can carry Razorpay payment links, and order updates can go out on WhatsApp.
How do we start?
Book a call or message us on WhatsApp. We will ask how orders, stock and accounts move today and suggest what the first release should cover.
