Why Finance, Inventory and Sales Must Work Together

Finance and inventory and sales are really connected to each other in any company.

Consider a typical customer order:

  1. A sales representative creates a quotation.
  2. Inventory availability must be verified.
  3. The order is processed.
  4. Inventory levels are updated.
  5. An invoice is generated.
  6. Payment is collected.
  7. Financial records are updated.

When all these things happen in systems it can cause problems and delays. Finance and inventory and sales must work together. An integrated system helps share information, between departments, which makes things more accurate and easier to do.
