CRM and ERP systems that match your business rules

A CRM manages customers and sales; an ERP manages operations such as orders, inventory and invoicing. Blocvibe builds custom CRM and ERP systems, or extends the ones you already use, so they follow your actual business rules.

The service

What is CRM and ERP development?

CRM and ERP development is building or extending the systems that run customers, sales, operations and finance. A CRM follows leads, customers and communication; an ERP covers orders, inventory, jobs and invoicing. Blocvibe builds focused custom systems and extends existing ones through their APIs.

Who it is for

  • Service businesses that follow work from lead to invoice
  • Companies whose pricing, approval or record rules generic tools do not cover
  • Teams whose CRM or ERP needs custom modules rather than replacing

When to consider it

  • One customer’s history is spread across several tools
  • Quotes and approvals happen in email and spreadsheets
  • Invoices are re-typed into the accounting system

The challenge

The business problem

Generic CRM and ERP tools often cover most of a business but miss the rules that make it different, such as custom pricing, approval steps or industry-specific records. Teams fill the gaps with spreadsheets, and information about one customer ends up in several places.

  • Generic systems miss the rules that make the business different
  • Leads, quotes, jobs and invoices are not connected to each other
  • Custom pricing lives in spreadsheets outside the system
  • Moving data from older tools looks risky

Our capabilities

How we help

  1. Model your rules

    Pricing, approvals and workflows are built to match how your business actually operates.

  2. One record per customer

    Leads, quotes, jobs and invoices connect so everyone sees the same history.

  3. Extend or build

    We can extend an existing CRM or ERP through its API, or build a focused custom system.

How it works

How a lead-to-invoice system connects

  1. Lead capture

    • Website forms
    • Phone and email enquiries
    • Imported lists
  2. CRM records

    • Contacts and companies
    • Pipeline stages
    • Activity history
  3. Operations

    • Quotes from your price rules
    • Approvals
    • Jobs, orders or stock
  4. Finance

    • Invoices from completed work
    • Sync to accounting software
    • Pipeline and revenue reports

Example workflow

Lead to invoice

  1. Step 1: A new lead arrives from your website or by phone and is logged with its source.

  2. Step 2: A quote is prepared from your price rules and sent for internal approval if needed.

  3. Step 3: Once accepted, the quote becomes a scheduled job with assigned staff.

  4. Step 4: Completed work is recorded with time and materials used.

  5. Step 5: An invoice is created from the job and synced to your accounting system.

Limits to keep in mind

Syncing with accounting software depends on that product’s API and plan. We confirm what is possible during discovery.

Industry applications

Where CRM and ERP development helps

Practical examples of how this service applies in different sectors.

These are illustrations of how the service can be applied, not descriptions of client projects. Our published projects are on the Our Work page.
  • Construction and Field Services

    The challenge
    Quotes are priced in spreadsheets, approved by email and re-typed into a job list once accepted.
    The solution
    A quote-to-job workflow with your price rules, approval steps and job scheduling in one system.
    How it works
    A lead becomes a quote from the price rules, goes for approval where needed, becomes a scheduled job when accepted and produces an invoice when the work is done.
    The benefit
    Each customer has one history from first contact to invoice, and pricing stays consistent.

    • REST APIs

  • Logistics and Fleet Management

    The challenge
    Customer contracts, rates and service levels are kept outside the system that handles bookings.
    The solution
    A CRM extension that holds contract rates and links them to bookings and invoicing.
    How it works
    Contract rates are stored for each customer, applied when a booking is made and carried through to the invoice.
    The benefit
    Invoices match the agreed rates, and account managers see each customer’s activity in one place.

  • Wholesale and distribution

    The challenge
    Stock levels, orders and customer pricing are checked in different places before an order can be confirmed.
    The solution
    An order and inventory module with customer-specific pricing.
    How it works
    An order is entered or imported, checked against stock and the customer’s price list, confirmed and passed on for picking and invoicing.
    The benefit
    Orders are confirmed without checking several systems, and stock records stay current.

Our development process

How the project runs

  1. Step 1: Discover

    We learn how your business works today, what is not working and what success should look like.

  2. Step 2: Define

    We agree on a written scope, priorities, estimate and timeline before any development begins.

  3. Step 3: Design and build

    The solution is designed and built in short cycles, with working software to review along the way.

  4. Step 4: Validate

    We test with your team and real or representative data, and fix what needs fixing before launch.

  5. Step 5: Deploy

    The solution goes live in your environment with documentation and a handover for your team.

  6. Step 6: Support and improve

    We monitor, maintain and improve the solution as your business and its users’ needs change.

How we work

Frequently asked questions

Should we build a custom CRM or extend an existing one?

If an existing CRM covers most of your needs, extending it is usually faster and cheaper. A custom system makes sense when your core process is unusual or the existing tool’s limits create constant workarounds.

Can you migrate our existing data?

Yes. Data is mapped, cleaned and imported, with a test migration reviewed before the final switch-over.

Will it connect to our accounting software?

Most accounting products offer APIs that allow invoices and payments to sync. Exact capabilities depend on the product and your subscription plan.

Which CRM and ERP systems can you extend?

Most modern CRM and ERP products offer an API that custom modules can use. Whether a specific product and plan allows what you need is confirmed during discovery.

Can different teams see different information?

Yes. Roles and permissions control which records and actions each team or person can access.
