Ten questions to answer first
Connecting Tally, Zoho, WhatsApp, a CRM and spreadsheets is mostly a set of business decisions. Answer the questions below before a first discussion with a developer, and the quote you get will be more accurate.
1. What do you use, on which plan?
For each tool, note the product and edition or plan, whether it’s cloud or installed on a computer, and who holds the admin login.
Plans matter, because many tools allow API access, or more API calls, only on certain plans. For Zoho, also note which data centre your account is on. Accounts on Zoho’s India data centre use India-specific API addresses, and a developer needs to know that.
2. Which system has the final word?
Decide the source of truth for each kind of data. Customers: the CRM or the accounts software? Products and prices: the website, the ERP or a sheet? Stock: the warehouse tool or Tally? Invoices and payments almost always belong to the accounts software.
When two systems both think they own a customer’s phone number, they overwrite each other.
3. Which way does data move?
One-way sync, such as new website orders flowing into accounts, is simpler and safer. Two-way sync, where edits in either system update the other, is far more work and needs rules for conflicts. Ask for two-way only where people really edit the same data in both places.
4. How fast must it be?
A new lead should reach sales within moments. Stock on a website might update every few minutes or hourly. A sales summary can be daily. Instant sync usually relies on webhooks, where a tool announces a change; slower sync checks for changes on a schedule. Faster isn’t automatically better. Match the speed to how the data is used.
5. How much data moves?
Give rough numbers: leads per day, orders per day, invoices per month. Volume decides which approach fits and whether API limits could become a problem.
6. How will records be matched?
Duplicates are a common integration headache. The same phone number arrives as 98xxxxxxxx, +91 98xxxxxxxx and 098xxxxxxxx. One company is spelt three ways. One customer buys for several branches.
Choose a matching key for each record type (a phone number in one standard format, the GSTIN, an email), and decide what happens when a match is uncertain: create a new record, or flag it for a person.
7. What happens when something fails?
Connections break. A password changes, an API goes down, a required field arrives empty. Decide who gets alerted and how, whether failed items retry automatically, where every sync is logged so you can see what moved, and what staff do manually until it’s fixed.
8. What about tools with no API?
Some tools offer no proper way in. The options, from most to least reliable: a scheduled export and import (CSV or Excel), the tool’s own file or database interface where one exists, and finally browser automation that works the tool’s web screens as a person would. That last option breaks when the screens change, so it needs watching.
9. Who owns the connection?
Create API keys and integration subscriptions in your business’s own accounts, so you stay in control if you change vendors. Agree who maintains the integration when a tool updates, where the integration code or workflows are kept, and make sure you can access them.
10. What personal data moves, and why?
Send each system only the fields it needs. A courier needs an address and phone number, and has no use for purchase history. With ID documents or health information, be stricter still, and note where each system stores what it receives.
Tool-specific notes
Connecting Tally
TallyPrime is desktop software. It can exchange data through its XML interface over the office network, and it supports ODBC for reading data. So an integration needs Tally running on a machine the integration can reach, or a hosted Tally setup.
In Tally, customers and suppliers are ledgers (masters), and sales, purchases and receipts are vouchers. When connecting Tally to a CRM, decide which ledgers sync and in which direction, and whether vouchers flow into Tally, out of it, or both. Party names and GSTINs need to match exactly, or you get duplicate ledgers.
Ask two more things early. How will the connection stay available when the office computer is switched off? And should entries post directly, or wait for your accountant to approve? For purchase and sales vouchers, approval first is often the safer start.
Connecting WhatsApp
Linking WhatsApp to a CRM or order system needs the WhatsApp Business Platform, which is a separate product from the WhatsApp Business app on a phone. Decide which number to use, in whose business account, and whether staff will still reply from their phones. A shared inbox is one answer: the shared WhatsApp inbox we built into Microsive ATS on the WhatsApp Cloud API lets the team reply from one place, with the candidate’s profile and stage beside the chat. Messages your business starts need approved templates (WhatsApp template rules).
The first thing we settle is who replies and from where. That one decision sets the whole design: which number the business uses, whose account it sits in, and whether replies come from a shared inbox or from staff phones.
Ways to connect
| Approach | Good for | Watch for |
|---|---|---|
| A built-in integration between two tools | Common pairs that already work together | Little control over fields and rules |
| A workflow platform (Zapier, Make, n8n, Activepieces) | Most business workflows at moderate volume | Usage costs; who maintains the workflows |
| Custom code using each tool’s API | High volume, complex rules, critical data | Needs developers to change it |
| Scheduled file export and import | Tools without an API | Delays; manual steps creeping back |
| Browser automation | Tools with no API or export | Breaks when screens change |
To choose between platforms, see our comparison of n8n, Zapier, Make and Activepieces.
Should you replace the tools instead?
Sometimes. If staff copy data between four tools to finish one job, a single custom app may be simpler. If each tool serves its own team well, connecting them usually costs less.
How Microsive connects tools
We connect tools through their APIs in code, or through a workflow platform. One option is MicroFlow, our self-hosted platform built on Activepieces, which includes browser automation through a Chrome extension. For Tally, Zoho or other software, we can connect where it offers an API or data export. Our integrations page explains the approach.
