Why choosing ERP software deserves a process
An ERP touches almost every person and transaction in your business, and it will probably stay in place for many years. Knowing how to choose ERP software carefully matters more than finding the most impressive demo. A system that looks powerful but does not fit your process, or that your team finds hard to use, will cost far more in workarounds than it saves.
This guide is deliberately vendor-neutral. Whether you end up with DotOne or another product, following these steps will help you make a decision you can defend to your partners, your team and yourself.
Step 1: Define problems before features
Start with the problems you want to solve, not a list of features copied from a brochure. Interview each department and write down where time is wasted, where errors occur and which decisions are made without reliable data.
- Sales: lost enquiries, slow quotations, unclear order status, credit overruns.
- Purchase and stores: shortages discovered late, excess stock, mismatched receipts.
- Production: no visibility of work in progress, unrecorded scrap, unclear capacity.
- Quality: inspections on paper, no link between rejections and batches.
- Accounts: re-entry of invoices, slow month-end, GST reconciliation effort.
- Management: reports assembled manually, profitability unclear by product or customer.
Rank these problems by business impact. The top few become the core of your evaluation and your first implementation phase.
Step 2: Write a requirements document
Turn the problems into requirements that a vendor can respond to. For each requirement, note whether it is essential, important or nice to have. Include your real documents: sample orders, BOMs, job cards, inspection sheets, invoices and the reports the owner reads every week.
Add the non-functional needs too: number of users and locations, mobile access, integration with Tally or other systems, data hosting preferences and the level of support you expect. A clear document is also the basis for fair price comparison; see ERP software pricing for how quotes are built.
Step 3: Shortlist vendors that fit your industry
Generic ERPs can be configured for many industries, but industry-specific systems often start much closer to your process. A plywood manufacturer needs veneer, core and pressing stages with sheet and square-foot conversions. A tape converter needs jumbo rolls, coating, slitting and rewinding. A distributor needs schemes, routes and fast billing.
- Industry experience: can the vendor explain your process in your terms without prompting?
- Deployment: cloud, on-premise or both, and how that matches your connectivity and IT capacity.
- Size fit: is the product built for businesses of your scale, or will you pay for unused complexity?
- Local compliance: GST, e-invoice, e-way bill and statutory reports handled and maintained.
- Support presence: who answers when something breaks, and in which time zone and language?
Three or four serious options are usually enough. More than that turns evaluation into a long, tiring exercise.
Step 4: Run scripted demos with your data
Standard demos are designed to impress. Scripted demos show fit. Give each shortlisted vendor the same scenarios in advance and ask them to demonstrate those, ideally with your own items and customers.
- Take a customer order through to dispatch, invoice, e-invoice and receipt.
- Raise a purchase from a shortage, receive goods with inspection and post the bill.
- Issue material to a work order, record output, scrap and rework, and show the cost.
- Transfer stock between two locations and show the effect on both.
- Show the owner dashboard and the report you currently build manually.
- Change a user’s permission and show what they can no longer see.
Invite the people who will use the system daily. A store keeper’s reaction to the goods receipt screen is worth more than any brochure.
Step 5: Score options with a weighted matrix
Assign weights to criteria based on your priorities, then score each vendor after the demos. Typical criteria include functional fit, ease of use, industry fit, integration capability, implementation approach, support quality, scalability and total cost of ownership.
For example, a manufacturer with frequent rejections might weight quality and traceability heavily, while a distributor with thin margins might weight billing speed, scheme handling and stock accuracy. Agree the weights before the demos, not after, so scores are not bent to fit a favourite.
A scoring matrix does not make the decision for you, but it exposes disagreements early and stops the loudest opinion or the lowest price from dominating. Keep notes on why each score was given so the reasoning can be revisited.
Step 6: Check implementation and support, not just software
Many ERP projects fail because of implementation, not product. Ask each vendor how they run projects: who will work on yours, how requirements are signed off, how data is migrated, how users are trained and what happens after go-live. Our implementation services page shows what a structured approach looks like.
Ask to speak with existing users in a similar industry where possible. Focus on how problems were handled, not just whether the project succeeded. Also confirm data ownership and exit terms: you should be able to export all your data in standard formats.
Step 7: Plan the rollout before you sign
The final step happens before the contract, not after it. Agree with the chosen vendor what the first phase includes, which modules follow, how long each phase is expected to take and what your own team must contribute. Write down the go-live criteria, such as stock reconciled, key reports verified and users trained, so everyone shares the same definition of done.
Name your internal ERP coordinator and key users now, and give them time in their schedules. Decide the cut-over date with your accountant, keeping clear of peak season and statutory deadlines. Confirm how change requests will be handled and priced once the project begins.
Finally, plan how you will measure success after a few months of use: faster order processing, more accurate stock, quicker month-end closing or better visibility of production. Measurable goals keep both sides focused on outcomes rather than on the number of screens delivered.
Mistakes to avoid when selecting ERP
- Choosing on price alone, then paying for customisation to close gaps.
- Letting one department, often accounts or IT, decide for everyone.
- Accepting a generic demo instead of your own scenarios.
- Ignoring usability for shop-floor and store users.
- Underestimating data cleanup and internal effort.
- Selecting features for a distant future while neglecting today’s problems.
If you want independent help with the process, our ERP consulting services include requirement mapping and vendor evaluation support.
Where AI fits into ERP selection
AI is now part of many ERP sales conversations. Treat it like any other feature: ask what it actually does with your data. Useful examples include agents that flag likely stock shortages, highlight overdue receivables, summarise production delays or answer management questions in plain language. DotOne includes such agents, described on the AI-powered ERP page.
AI cannot fix bad data or a broken process, so weigh it after core fit, usability and support rather than ahead of them. Ask the vendor to show an AI feature working on realistic data during the scripted demo, and check whether its suggestions can be traced back to the underlying transactions.
