MAKIN 
Pick boring where it touches money.
Payments, invoicing and payroll should be the least interesting parts of your stack. Choose the option your accountant already knows, that files what the law expects, and that a replacement hire can operate on day one. Save the appetite for novelty for places where a bug costs a retry rather than a penalty.
One system of record per kind of fact.
Customers live in one place. Inventory lives in one place. Money lives in one place. Everything else reads from those. The stacks that collapse under growth are the ones where three tools each hold a partial customer and a nightly job pretends they agree.
Buy the commodity, build the edge.
Nobody wins because their helpdesk is bespoke. Buy anything a competitor could buy too. Build only the part that is genuinely how you work — the pricing logic, the routing rule, the quality check that reflects your actual process. That is usually five percent of the stack and most of the value.
Plan the exit before the entry.
Before adopting anything, ask how the data leaves. A tool with a clean export and a documented API is a reversible decision; one without is a mortgage. You will change half this stack within four years, and the cost of that change is decided the day you sign up.
Money: accounts, payments and payroll
Apply the boring rule literally. For accounts, use the package your accountant already works in, whether that is Tally, Zoho Books or something else. For payments, a mainstream gateway that takes UPI, cards and net banking and produces settlement reports your accounts team can match to bank credits. For payroll, software that handles statutory deductions and payslips, so a new hire can run it from the manual. Whatever you choose in this layer, check these before you commit:
- Your accountant can use it without training
- Ledgers and vouchers export in a format another package can import
- Settlement reports reconcile to the bank statement line by line
- Access splits cleanly into people who enter, people who approve and people who only read
Customers and operations: one home each
The customer record lives in a CRM, not across a CRM, an inbox and a salesperson’s phone. Off-the-shelf options such as Zoho CRM or HubSpot cover standard sales processes; a custom build earns its keep only when your routing or quoting is the part competitors cannot copy. WhatsApp conversations should land in that same record through the WhatsApp Business platform, not on one employee’s handset.
Inventory follows the same rule. If your accounting package tracks stock well enough, keep it there. If you need a separate inventory or order system, make it the only owner of stock quantities and let accounts read from it, never both at once.
The glue: integrations, reporting and access
Integration is where stacks turn fragile. Prefer documented API connections, or one workflow tool everyone knows the location of, over scripts scattered across someone’s laptop. Every connection needs an owner, a log and a sentence saying which system is the source. Reporting reads from the systems of record and writes to nothing: Google Sheets is fine for a while, and Power BI or Looker Studio earns its place once several people need the same refreshed numbers.
Access is the part nobody plans until someone leaves, and by then the only admin login belongs to the person walking out of the door. Set these up on the first day, while the stack is small enough for it to be a quick job rather than a project:
- Company email on your own domain for every tool sign-up, never personal accounts
- A password manager with shared vaults, so no credential lives in a chat thread
- Single sign-on wherever a tool offers it, so offboarding happens in one place
- Admin rights held by more than one named person inside the business
Where building is worth it
The edge is the part of the stack that encodes a decision only you make. It is usually small, and a good place to look for it is the spreadsheet with formulas only one person understands. That spreadsheet is the signal: it is where the business logic sits, and it is the first part worth moving into proper software, with tests and a named owner. Typical candidates:
- A quoting or pricing engine that applies your real discount and margin rules
- Lead or job routing that depends on territory, skill or capacity
- A quality check specific to how your process actually runs
- A customer or partner portal showing status drawn from your own systems
The exit test, as a checklist
Run this list before any new tool gets a company card. If you cannot answer a line, treat it as a no until the vendor shows you otherwise. The same list works for tools you already pay for, and it is a quick way to find the ones that have quietly become a mortgage.
- Can we export every record, including history, notes and attachments, without asking support?
- Is the export in a standard format such as CSV or JSON, with IDs that link records together?
- Is there a documented API, and does our plan include access to it?
- Is the admin login tied to the company rather than to a person?
- What happens to our data when we stop paying, and how do we retrieve it?
- Could we run the old and new tools side by side while we switch?
Reviewing the stack you already have
Start with an inventory, not a wish list. Write down every tool, the kind of fact it holds, who owns it, who pays for it and what reads from it. Then group by fact: customers, stock, money, people. Any fact with more than one home is your first project. Any tool nobody owns is your second. Any connection nobody can explain is your third.
If you want a second pair of eyes on that map, the Tech Strategy Consultation starts at ₹3,000 and includes a current-state audit of the systems you already run and a target architecture to move towards. If a business you are buying comes with its own software, Technical Due Diligence, from ₹23,000, is the closer fit.
