Implementing a CRM system? We migrate your data, train your team and support you after go-live.

Integrations

QuickBooks Desktop integration

Our QuickBooks Integrator is a desktop tool that keeps QuickBooks Desktop and your web application in two-way sync. After registration and an initial upload of your existing QuickBooks data, every create, update or delete on either side flows to the other, using the field mapping you choose.

What it keeps in sync

  • Customers, vendors and employees
  • Chart of accounts and items
  • Invoices, sales orders and purchase orders
  • Payments received, bills, credits and payments made

A small web service on your server connects the tool to your application database, and custom rules map records the way your business works, for example creating a QuickBooks vendor as a contractor in a specific sales office. See it in the QB Desktop case study.

Integrations

3rd party integrations

Most businesses run on several systems that do not talk to each other. We connect your software with third-party platforms through their APIs, so data moves automatically and your team stops copying it by hand.

Systems we connect

  • Accounting software such as QuickBooks Desktop
  • Payment gateways and online payments
  • E-commerce platforms and online stores
  • Shipping, courier and GPS tracking services
  • Email, SMS and WhatsApp messaging
  • Your existing CRM, ERP and internal tools

See our integration work in the Book Connector and QB Desktop case studies.

CRM system

What is a CRM system?

A customer relationship management (CRM) system manages every interaction with your current and potential customers. It keeps each customer’s history in one place, so sales, support and management see the same picture and can focus on retention and sales growth.

What a custom CRM system does for you

  • Builds prospect profiles and tracks their needs from first enquiry onwards
  • Keeps contacts, purchases, quotes and support tickets in one database
  • Connects front-office sales with back-office accounting and ERP
  • Shows pipeline, follow-ups and customer value in live reports

See a CRM we built in the Sonic CRM case study.

ERP system

ERP system development services

Enterprise resource planning (ERP) software brings your business processes into one system with a central database. We build custom ERP systems that replace spreadsheets and disconnected tools, so information flows between departments and to outside partners without re-entry.

A custom ERP is built around how your business works, and it can grow module by module instead of forcing you into a generic package.

ERP modules we build

  • Inventory, purchasing and warehouse management
  • Sales orders, invoicing and payments
  • Production planning and cost accounting
  • HR, payroll and attendance
  • Dashboards and reports for management

ERP integration

We connect your ERP with CRM, e-commerce, payment gateways and accounting software such as QuickBooks Desktop. See our Image Processing ERP, Cost Accounting System and GunaAgro projects, or read about ERP integration for school management software.

FAQ

Frequently asked questions

What are custom software development services?

Custom software development services cover designing, building, integrating and supporting software made for one business, instead of buying a generic package. It usually includes discovery, UX design, development, testing, deployment and maintenance.

Should we buy CRM software or build a custom CRM?

Off-the-shelf CRM suits standard sales processes. A custom CRM system is better when your workflow, products or approvals are specific, when you need deep integration with ERP or accounting, or when per-user licence costs grow too high.

Can you combine CRM and ERP in one system?

Yes. Many of our clients run a single platform from enquiry and quote to order, inventory, invoice and payment, which removes double entry between systems.

Which technologies do you use?

We use PHP/Laravel, .NET/C#, Java, React, Angular, Flutter, MySQL and SQL Server, hosted on the cloud of your choice. We pick the stack that fits your team and long-term support.

Do you work with start-ups?

Yes. We build MVPs and SaaS products for start-ups and scale the team as the product grows.

How do you protect our code and data?

ACS is ISO 27001 certified. We sign NDAs, you own the source code, and access to systems and data is role-based and logged.

What is the best CRM for small companies?

The best CRM for small companies is one the team actually uses: simple pipelines, email and WhatsApp integration and clear reports. ACS configures or builds a CRM for small business that fits your process and can grow with you.

Do you offer web app development services?

Yes. As a web application development firm we build SaaS products, portals and internal tools, from design and development to hosting and support.
