In the previous article, we learned how Business Central generates Billing Proposals and converts eligible subscription lines into recurring invoices. That process works perfectly when subscription contracts remain unchanged.
However, subscription businesses are dynamic. Customers frequently upgrade or downgrade plans, change quantities, purchase additional services during an active billing cycle, or terminate services before the contract ends. These changes directly impact recurring billing and revenue calculations.
Microsoft Dynamics 365 Business Central provides flexible pricing and billing adjustment capabilities to handle these real-world subscription scenarios without disrupting contract history or financial accuracy.
In this article, we'll explore how pricing, discounts, proration, and billing adjustments work throughout the subscription lifecycle.
Understanding Subscription Pricing
Pricing is the commercial foundation of every subscription contract. Every subscription line contains pricing information that Business Central uses during recurring billing. Instead of manually entering prices for every billing cycle, the subscription contract stores the recurring amount together with billing frequency, quantity, and service duration.
The pricing structure can differ depending on the organization's business model. Some subscriptions have a fixed recurring fee, while others vary based on quantity, usage, or contractual agreements.
A well-designed pricing strategy ensures predictable recurring revenue and simplifies future contract amendments.
Fixed Pricing vs Variable Pricing
Business Central supports different pricing approaches depending on the subscription offering.
Fixed Pricing
Fixed pricing is the simplest subscription model. The customer pays the same amount during every billing cycle until the contract changes.
Examples include:
> SaaS license billed monthly.
> Annual maintenance contract.
> Membership subscription.
> Managed support agreement.
The recurring billing process automatically generates the same amount during every billing period.
Variable Pricing
Variable pricing allows recurring amounts to change during the contract lifecycle.
This is useful for scenarios where pricing depends on:
> Number of licensed users.
> Devices under management.
> Storage consumption.
> Service quantity.
> Contract amendments.
Variable pricing provides flexibility while still keeping the subscription under one customer contract.
Subscription Price Updates
Subscription prices don't always remain constant throughout a contract. Organizations may increase prices due to annual revisions, introduce promotional pricing, or negotiate customer-specific pricing.
Instead of creating a new subscription contract every time prices change, Business Central allows price updates on subscription lines so future billing reflects the revised amount while preserving historical invoices.
This ensures that invoices already posted remain unchanged while future recurring billing uses the updated pricing.
Example
Billing Period | Monthly Price |
|---|
January – June | $500 |
July onwards | $600 |
Business Central continues to preserve previous billing history while applying the new price from the effective date.
Customer-Specific Pricing
Many organizations negotiate custom pricing for strategic customers. Business Central supports customer-specific pricing through subscription contracts rather than modifying the reusable subscription package.
This allows organizations to maintain standardized subscription offerings while applying negotiated commercial terms only where required.
For example:
| Customer | Subscription Plan | Monthly Price |
|---|
| Customer A | Premium Support | $500 |
| Customer B | Premium Support | $450 (Negotiated) |
| Customer C | Premium Support | $550 (Regional Pricing) |
This approach keeps subscription packages reusable while supporting flexible customer pricing.
Applying Discounts to Subscription Contracts
Discounts are common in subscription businesses, especially during onboarding campaigns or renewal negotiations.
Business Central allows discounts to be applied directly to subscription lines, influencing future recurring billing calculations.
Discounts may be:
> Percentage-based.
> Fixed amount.
> Customer-specific promotional discounts.
> Renewal discounts.
> Long-term contract incentives.
Example
Subscription | Original Price | Discount | Customer Pays |
|---|
Cloud Hosting | $1,000 | 10% | $900 |
Security Monitoring | $500 | $50 | $450 |
Premium Support | $300 | 20% | $240 |
During recurring billing, Business Central automatically calculates the invoice using the active discount configuration.
Promotional Pricing and Introductory Offers
Subscription businesses often offer introductory pricing to attract new customers.
Examples include:
> First month free.
> 50% discount for the first three months.
> Annual plan with one complimentary billing cycle.
Instead of permanently reducing the subscription price, organizations can manage promotional pricing through contract amendments or billing adjustments so that standard pricing resumes after the promotional period.
This provides flexibility without affecting long-term contract pricing.
Understanding Proration
Proration is one of the most important concepts in subscription billing.
Proration occurs when a subscription starts, ends, or changes during a billing period instead of at the beginning or end of the cycle.
Rather than charging the customer for a complete billing period, Business Central calculates the amount proportionally based on the service duration.
Example
Monthly subscription price:
$300
Billing period:
1 August – 31 August
Customer starts subscription on:
16 August
Instead of charging the full $300, Business Central calculates the charge only for the remaining days in August according to the configured billing rules. Proration ensures fair billing for both customers and the organization.
Mid-Cycle Upgrades
Customers frequently upgrade subscriptions before the current billing period ends.
Business Scenario
A customer currently subscribes to:
Standard Support – $400/month
On the 15th of the month, they upgrade to:
Premium Support – $650/month
Business Central handles this scenario by calculating the billing adjustment for the remaining portion of the billing cycle. The customer receives an invoice reflecting only the difference for the remaining service period instead of paying the entire Premium amount again.
This creates a seamless customer experience while maintaining accurate recurring revenue.
Mid-Cycle Downgrades
Downgrades work similarly but in the opposite direction. Suppose a customer moves from a Premium subscription to a Standard subscription before the billing period ends.
Instead of immediately charging the lower price for the entire month, Business Central calculates the appropriate credit or reduced billing amount for the remaining service period.
This prevents overbilling and keeps billing aligned with the customer's active subscription level.
Adding Additional Subscription Services
Customers often expand their subscriptions during an active contract.
Example
Existing Contract:
> Cloud Hosting
> Premium Support
> Customer Adds:
> Security Monitoring
> Backup Service
Rather than creating a separate subscription contract, new subscription lines can be added to the existing contract.
Future billing proposals automatically include the newly added services according to their configured billing dates.
This keeps the customer relationship centralized under one contract.
Removing Subscription Services
Sometimes customers discontinue only one recurring service while keeping the rest of the subscription active.
Business Central allows individual subscription lines to end without closing the entire contract.
Example
Customer Removes:
Backup Service
Remaining Services Continue:
> Cloud Hosting
> Premium Support
> Security Monitoring
Future recurring billing excludes the discontinued service while continuing to invoice the remaining subscription lines.
Billing Adjustments
Billing Adjustments ensure invoices accurately reflect contractual changes.
Adjustments may occur due to:
> Price revisions.
> Quantity changes.
> Billing corrections.
> Promotional discounts.
> Contract amendments.
> Manual commercial agreements.
Instead of modifying posted invoices, Business Central creates the necessary billing adjustments during future billing cycles or through credit documents when required.
This preserves financial history while maintaining accurate customer balances.
Credit Memos for Subscription Billing
Credit Memos play an important role when customers are entitled to refunds or billing corrections.
Common scenarios include:
> Customer cancels service before the billing period ends.
> Duplicate billing occurred.
> Incorrect quantity billed.
> Promotional credit applied after invoicing.
Business Central creates subscription-related credit memos that reverse or reduce customer charges while maintaining a complete audit trail.
This is significantly better than manually editing posted invoices.
Handling Contract Amendments
Contract amendments allow organizations to modify commercial agreements without recreating subscription contracts.
Amendments may include:
> Price increase.
> Price decrease.
> Quantity revision.
> Additional subscription lines.
> Removal of services.
> Billing frequency changes.
Business Central maintains historical billing information while applying new contractual conditions from the specified effective date.
This is particularly valuable for long-term customer agreements where services evolve over time.
Real-World Business Scenario
Imagine an IT services company offering a Business Premium Subscription.
Initial Contract
Service | Monthly Price |
|---|
Microsoft 365 License | $250 |
Premium Support | $150 |
Cloud Backup | $100 |
Total | $500 |
After three months, the customer requests additional cybersecurity monitoring.
Contract Amendment
Additional Service | Monthly Price |
|---|
Cybersecurity Monitoring | $120 |
New recurring monthly billing becomes $620.
Midway through the next billing cycle, the customer upgrades storage capacity, resulting in another prorated billing adjustment.
Business Central automatically includes the new service and adjustment in the next billing proposal while preserving previous invoices for audit purposes.
Best Practices for Pricing and Billing Adjustments
> A successful subscription pricing strategy depends on maintaining consistency while allowing flexibility for customer-specific agreements.
> Organizations should avoid editing posted invoices directly. Instead, use subscription contract amendments and billing adjustments to preserve audit history.
> Keep reusable subscription packages free from customer-specific pricing wherever possible. Customer negotiations should be handled at the contract level.
> Review billing proposals after significant pricing or quantity changes to verify prorated calculations before posting invoices.
> Document pricing policies for renewals, upgrades, and promotional offers so finance and sales teams follow a consistent process.
Common Mistakes to Avoid
Many organizations encounter billing issues because subscription pricing isn't managed correctly.
Common implementation mistakes include:
> Updating reusable package prices instead of contract prices.
> Manually editing recurring invoices after billing proposals.
> Ignoring proration for mid-cycle contract changes.
> Applying permanent discounts instead of promotional adjustments.
> Creating duplicate subscription contracts instead of amending existing contracts.
Avoiding these mistakes improves billing accuracy and customer satisfaction.
Key Takeaways
> Subscription pricing can be fixed or variable depending on the business model.
