Connecting Your Website to a CRM and ERP: How to Stop Losing Leads Between Spreadsheets

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”.

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

1. Entry point. Site form, live chat, tap-to-call, Telegram/WhatsApp enquiry, store cart.
2. Deal creation. Data flows to the CRM via API: contact + deal + source + UTM. No manual transfer.
3. First step. An auto-task to the manager, an auto email/SMS to the customer, a call recording in the record.
4. Documents. An invoice is generated from the deal by template; for e-commerce, sync with the ERP on order and payment.
5. Statuses. Shipment and delivery from the ERP flow back to the site/customer notification.
6. 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 $4,300)

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 numbers

• OptiCRM — a wholesale company: a custom CRM on React + Node.js with a “lead → invoice → shipment → payment” pipeline, telephony with call recording and live margin dashboards. Result: −35% deal cycle, three tools replaced by one, every communication in one place.
• Solomia Beauty — a store: a 2-step checkout + live stock sync and a CRM customer card → zero lost leads and +180% conversion.
• Flowmatic — an automation platform: lead → deal → contract → payment with no manual steps → −280 person-hours of routine per month.

What it costs and how long it takes

Work	Timeline	Budget guide
Form/chat → CRM + alerts	3–7 days	from $400–700
Site ↔ ERP (stock, orders, payment)	2–5 weeks	from $1,000 per loop
Custom CRM for your process	6–14 weeks	from $4,300

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.

Bottom line

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.
