Your entire operation in one system

You choose where to start. Each module is a delivery milestone that goes into real use while the next one is built.

Accounts payable and receivable, projected cash flow, automatic bank reconciliation and cost centers.

Tax Module

Issuing of electronic invoices (NF-e, NFS-e, MDF-e), automatic tax calculation and direct export to accounting.

Production & Services

Production or service orders, time tracking, materials traceability and cost per project.

Records & Access

Customers, suppliers, products and a strict permissions table by team role and branch.

Integrations & APIs

Native connection with e-commerce stores, marketplaces, banking gateways, carriers and legacy systems.

When sales live in your salespeople's heads

The symptom is always the same: nobody can say exactly how much will be billed this month without asking each salesperson.

Without your own centralized CRM

  • ✕ Each salesperson manages contacts and customers on their personal WhatsApp.
  • ✕ When a salesperson leaves, the history and the customer leave with them.
  • ✕ The closing forecast is a guess revised in a rush every week.
  • ✕ Commissions are calculated in manual spreadsheets, with discrepancies every month.

With a custom GoAppy CRM

  • ✓ The customer portfolio is a protected company asset, not the salesperson's.
  • ✓ Complete history of proposals, messages and meetings on a single screen.
  • ✓ Real-time revenue forecast calculated from the actual sales funnel.
  • ✓ Commissions calculated automatically according to the company's contractual rules.

Visual sales funnel (Kanban)

Each deal in a clear stage, with opportunity value, owner and expected close date.

Lead capture and history

Automatic intake from the website and WhatsApp, distribution among agents/salespeople and a unified history.

Follow-up and sales cadence

Automatic reminders so no proposal goes cold, plus automatic commission calculation per sale.

Switch systems without stopping your business

The legitimate fear of anyone who has seen a software migration fail is losing control of the operation halfway through.

That's why no project starts with an abrupt switch. The new system is introduced in gradual modules, integrated with what's still running, operating in parallel until your team confirms that 100% of the data and numbers match.

  • Staging environment with real data before each switchover.
  • Parallel operation until the accounting and operational checks are complete.
  • Hands-on user training on the delivered module.
  • Documented contingency and rollback plan for zero risk.
