Spreadsheets are wonderful until three people edit the same row, the formula breaks, and last month’s invoice file is named final_v7_REAL.xlsx.
If your operations live there, you do not need a 40-module ERP on day one. You need a working system your team will actually open every morning.
Step 1 - Inventory the chaos List every sheet and chat group that runs the business. Be honest. Include the “temporary” tracker that has been temporary for two years.
Step 2 - Rank by risk What causes money loss or client embarrassment first? Usually: billing, lead follow-up, delivery status. Start there.
Step 3 - Design the happy path Write the ideal day: lead comes in → recorded → quoted → approved → work tracked → invoice sent → paid. Cross out anything that is vanity.
Step 4 - Replace one lane at a time Move billing first, or CRM first - not both plus HR plus inventory. Parallel run the old sheet for two weeks if needed, then lock it as read-only.
Step 5 - Make the new way easier than the old way If logging a payment takes longer than a WhatsApp message, people will cheat. Mobile-friendly screens, few required fields, and clear status labels matter more than fancy charts.
What we usually ship first For service businesses: clients, projects, GST invoices, and a simple client login. That alone removes half the “where is my invoice?” noise.
If you are stuck between “keep Excel forever” and “big transformation,” book a discovery call. Bring one painful workflow. We will sketch the first release with you.
