ERP for Manufacturing SMEs: Build, Buy or Customise

Manufacturing SMEs should buy a packaged ERP when their processes are close to industry standard, customise one when a few processes differ, and build custom modules when production, costing or quality control is genuinely distinctive and central to how they win orders. Many do best with a hybrid: packaged accounting and inventory, plus custom software for the parts that make them different.

Why ERP decisions go wrong

ERP projects in small and mid-sized manufacturers often run late and over budget for familiar reasons:

• The software was chosen from a demo, not from a map of how the factory works.
• Every department wanted every feature on day one.
• Data from spreadsheets and Tally was migrated without cleaning.
• The shop floor was never consulted, so people kept their old registers.

Before choosing between build and buy, map your processes from enquiry to dispatch.

Option 1: Buy a packaged ERP

Packaged ERPs cover sales orders, purchase, inventory, production orders, costing and accounts in one system.

Suits you when: your production follows common patterns, such as make-to-stock or simple make-to-order, and you are willing to adapt your process to the software.

Watch for: per-user licence costs as you grow, costly customisation, and features you pay for but never use.

Option 2: Customise a packaged ERP

Most ERPs allow custom fields, reports and workflows, and some allow deeper extensions.

Suits you when: 80 to 90 percent of your process fits, and a few areas, such as a specific quality check or a costing method, need adjustment.

Watch for: customisations that break during upgrades, and dependence on one implementation partner.

Option 3: Build custom modules

A custom system is designed around your exact workflow: how you quote, schedule, track work in progress and cost each job.

Suits you when:

• You make engineered or configured products where every order is different.
• Quotations depend on complex technical rules.
• Your scheduling and job tracking are where you beat competitors.
• Licence costs for your headcount would exceed the cost of building.

Watch for: the need for a reliable partner for maintenance, and the temptation to rebuild commodity functions such as accounting.

The hybrid approach

For many Indian manufacturers the most practical design is:

• Accounting and GST in Tally or a proven accounting system.
• A custom operations layer for enquiries, quotations, job cards, production tracking and dispatch.
• Integrations that sync customers, invoices and payments between the two.

This keeps compliance in trusted software and puts your investment where it creates an advantage.

Questions to ask before you choose

Put these to every ERP vendor and every custom development partner:

• Show us our process in your system. Bring a real order from enquiry to dispatch, including a change request and a partial delivery, and ask them to walk it through.
• What does it cost at our headcount in three years? Include licences, add-ons, hosting and support.
• How are customisations handled during upgrades? Ask for an example of an upgrade that broke a customisation and how it was fixed.
• Who will implement it, and how many similar factories have they done?
• How will shop-floor staff enter data? If the answer is a desktop screen, adoption will suffer.
• How does it connect to Tally or our accounting system? Get specifics, not "via API".
• What happens to our data if we leave? You should be able to export everything in usable formats.

The quality of these answers often tells you more than the feature list.

A phased plan

1. Process mapping (2 to 3 weeks). Enquiry to dispatch, including exceptions.
2. Phase 1: the biggest pain. Often quotations or production tracking.
3. Phase 2: connect to accounts. Tally or your accounting system.
4. Phase 3: planning and reporting. Scheduling, capacity and leadership dashboards.

Each phase goes live before the next begins, so the business sees value within months, not years.

Frequently asked questions

Can we keep using Tally with a new ERP?

Yes. Many manufacturers keep Tally for accounts and connect it to operational software. See our guide to Tally integration.

How long does an ERP project take?

Packaged ERP implementations for SMEs typically take three to nine months. Phased custom builds deliver the first module in two to four months.

What about shop-floor data entry?

Tablets or mobile apps at workstations, with simple screens and barcodes, work better than asking operators to use desktop software.

Is custom ERP risky?

It carries risk if it is built all at once. Phased delivery with a partner who owns maintenance keeps the risk manageable.
