This guide walks through a scope amendment step by step, next to the engineering software your team already uses for design and calculation. By following this guide, your team can verify how the system handles contract modifications, ensuring that all additional work is properly recorded and tracked through your standard business workflows.
Key facts
CRM for engineering firms at Workspace369 covers 9 areas, including client records, proposals, projects and tasks.
The workflow runs in 5 steps, from "update client records and brief" to "issue amending invoices".
Workspace369 starts at $29/mo for 1 seat, and the Commander plan includes 20 seats and 12× Cadet usage at $299/mo.

AEC platforms lead for phase and project billing: BQE Core and Deltek Ajera quote prices on request, and Monograph's calculator shows $600 to $750 a month at 10 employees. Productive and Harvest cover billable time from $10 and $9 per user a month billed yearly. Workspace369 fits a small firm that wants Proposals, deposits, payment schedules and time-to-invoice from $29 a month, but it has no percent-complete billing.

When a client requests an additional engineering discipline after the initial contract is signed, project managers often drop the request into email threads. Without updating the primary client records or creating a new proposal, the engineering firm performs unbilled work. Administrative staff cannot verify if the new discipline is accounted for in the active project tasks or if files are correctly organized for the extra scope.
Discussions regarding a new engineering discipline usually happen across multiple phone calls and personal text messages. When these conversations are not logged alongside client records, project teams miss critical constraints. The project manager records in the brief what structural or environmental parameters changed, ensuring that the updated scope is visible before scheduling subsequent design reviews or drafting new project tasks.
If an engineering firm adds a discipline to a commission without issuing a separate proposal, invoices rarely match the actual engineering hours delivered. Administrative teams lack clarity on whether to issue a brand-new invoice or amend the existing billing schedule. Without a clear link between projects, tasks, and invoices, firms lose revenue on additional engineering services due to poor documentation.
Adding a new discipline means managing additional technical files, calculations, and reports. If these files are saved in isolated local folders instead of being linked to the central project record, team members work off outdated information. Scope documents and project files must be accessible alongside conversations to prevent costly design mismatches.
Clients watch progress, files, and invoices in a branded portal instead of asking your team for updates.
Email lands beside the client record on every plan; texts, calls and voicemail join it from Voyager, with AI call summaries from Specialist.
Tasks, files, and status for every engagement — visible to the team and, through the client portal, to the client.
Send quotes, bill milestones or retainers, and let automated reminders chase anything outstanding.
When an engineering client requests an additional discipline after the initial scope approval, an operator opens the client records right away. The operator records in the brief that a new engineering discipline has been requested, noting the date, the specific discipline added, and any initial constraints discussed during the preliminary conversations.
Draft a new proposal within the system specifically covering the fees and scope of the added engineering discipline. This proposal must detail the extra tasks and deliverables required. The operator adds the relevant scope files and sets a review deadline on the calendar, and the client approves and e-signs the proposal through its public link or the client portal.
Once the client approves the proposal, the operator updates the active project. Create a new set of tasks dedicated to the added engineering discipline. These tasks define the milestones for the added discipline, such as internal review schedules and file delivery dates.
Link all subsequent conversations regarding the new engineering discipline directly to the project record. The operator uploads correspondence, scope clarifications and supporting files into the project files section. This ensures that any team member on the project can verify the current scope boundaries by reviewing the logged conversations.
Based on the approved proposal for the additional discipline, generate the corresponding invoices within the system. The operator must verify that the invoice line items match the newly created project tasks and the updated client records. Send the invoices through the client portal, where the client can pay online, and track payment status on the project.

Keep design, technical calculations and structural analysis in your firm's engineering software, where professional compliance, accuracy and safety checks belong. Workspace369 runs the commercial side of each commission: client records, proposals, project tasks, files, conversations and invoices.
An operator updates the client records and records in the brief that an extra discipline was introduced. You then draft a new proposal, generate specific project tasks for the new milestones, log relevant conversations, and issue distinct invoices to account for the expanded scope of the engineering commission.
Clients approve and e-sign proposals and scope amendments through a public approval link. Professional engineering sign-off follows your licensed engineers’ own process, and the client portal holds the proposals, task schedules, files, conversations and invoices around it.
Files attach to the specific project for each discipline, with file versioning to keep revisions in order. Agree clear naming conventions by discipline so the project files section stays orderly.
Start with the modules you need today, then turn on AI, automations, accounting, inventory, requests, and reporting as the operation grows.
