Connecting Your Website to CRM and ERP: No Lost Leads
Leads are lost after the site, not on it. How to wire your website into CRM and ERP: the lead-to-invoice flow, integration types, mistakes and cost.
Short answer: a beautiful site is useless if its leads land in a shared inbox and get lost. Connecting the site to a CRM and ERP closes the end-to-end “lead → deal → invoice → fulfilment → payment” flow, where every enquiry automatically creates a record and the manager gets an alert in seconds. The most money leaks exactly at the seam between “website and accounting system”.
Where the money leaks
A customer sends a lead at 22:40 → the email drowns in the inbox → the manager sees it in the morning → the customer already bought from whoever replied first. Without an integration, 20–40% of leads are lost this way. With a “site → CRM → alert” flow, they physically can’t be lost.
What the site + CRM + ERP stack gives you
- Zero lost leads. Form, chat, call, messenger enquiry — everything lands in the CRM as a deal with a source.
- Instant response. An alert to the manager in Slack/email within seconds, an auto-reply to the customer, an auto-task.
- Live prices and stock. The catalogue on the site syncs with your ERP — no manual operator.
- A transparent pipeline. You see how many leads, from where, at what stage and how much they brought in.
- Cross-channel analytics. From the ad click to the paid invoice in one system.
How it works: the end-to-end flow
- Entry point. Site form, live chat, tap-to-call, Telegram/WhatsApp enquiry, store cart.
- Deal creation. Data flows to the CRM via API: contact + deal + source + UTM. No manual transfer.
- First step. An auto-task to the manager, an auto email/SMS to the customer, a call recording in the record.
- Documents. An invoice is generated from the deal by template; for e-commerce, sync with the ERP on order and payment.
- Statuses. Shipment and delivery from the ERP flow back to the site/customer notification.
- Analytics. A dashboard: leads → deals → revenue by channel and manager.
Types of integration — from simple to custom
| Level | What we connect | When it fits | Limits |
|---|---|---|---|
| Form → CRM | leads from forms and chat into an off-the-shelf CRM (HubSpot, Pipedrive) | fast start, low volume | rigid CRM scenario, paid add-on modules |
| Site ↔ ERP | stock, prices, orders, payments | e-commerce, wholesale, distribution | needs clean ERP catalogues |
| Telephony + email → CRM | calls and emails into the customer record | phone/email sales | integration and permission setup |
| Custom CRM | the whole process shaped to your scenario | when the process is your edge | pricier upfront (from $3,614 (₴150,000)) |
We start with a process map: showing exactly where leads and hours leak, and choosing the minimum sufficient stack — not “integrate everything at once”. Details on the CRM & automation page.
Cases: what changes in the work
All three are real DEXA projects — so this is a description of how the system is arranged, not a set of percentages “after rollout”: the rollout numbers are the clients’ own and are not published.
- OptiCRM — a wholesaler: a custom CRM on React + Node.js with the “lead → invoice → shipment → payment” pipeline, call-recording telephony and margin dashboards. Three services paid for in parallel replaced by one: the whole communication history sits in a single place.
- Solomia Beauty — a store: 2-step checkout plus live stock sync and a CRM customer card → no enquiry drowning in a chat thread.
- Flowmatic — an automation platform: lead → deal → contract → payment with no manual steps, with logs and reminders.
Typical integration mistakes
Leads go to a shared “for everyone” inbox — nobody replies because “it’s not mine”.
They connect the site but don’t clean up the ERP: messy catalogues turn sync into daily manual cleanup.
No process owner: the CRM fills for a week, then dies.
Connecting everything at once: 5 simultaneous loops = a blown project. Do one end-to-end scenario, then scale.
Not tracking lead source: without UTM and CRM capture, you can’t tell which channel pays back.
What it costs and how long it takes
| Work | Timeline | Budget guide |
|---|---|---|
| Form/chat → CRM + alerts | 3–7 days | from $361 (₴15,000) |
| Site ↔ ERP (stock, orders, payment) | 2–5 weeks | from $964 (₴40,000) per loop |
| Custom CRM for your process | 6–14 weeks | from $3,614 (₴150,000) |
The exact number depends on which systems you connect and how clean the data is. After a 30-minute call we give a fixed quote — as with all services on the pricing page.
We have a home-grown database from 2014 — is it worth integrating or easier to replace?
Integrating is worth it if the database is alive and holds data: an API or document-exchange link is cheaper than migration. Replace it with a custom CRM when it slows processes and isn’t mobile-accessible — as in the OptiCRM case, where three tools became one.
Off-the-shelf CRM or custom?
A boxed CRM is faster and cheaper to start but forces you to bend processes around it. A custom CRM is built to your scenario and pays back when the process is your competitive edge. Comparison in how to choose a CRM and CRM or spreadsheet.
Do I need an integration if leads are few?
Even at 10 leads a day, one in four is lost to a slow reply. The minimum “form → CRM → Slack/Telegram alert → auto email” flow takes days and pays back with the first saved deals.
Where to start
Connecting your site to a CRM and ERP turns scattered “emails and spreadsheets” into a managed deal flow where no lead is lost. Start with a process map and one end-to-end scenario — then scale by ROI.
