How customer drawing approvals gate production
In engineered-to-order work, the approved drawing is the contract. Here is how ARKcelerate makes the approved revision drive the shop floor — and what happens when an approval runs late.
For engineered-to-order and project-based manufacturers, fabrication cannot start until the customer has approved the drawing — and it has to be the right revision. Get that wrong and you cut steel to a superseded drawing, which means scrap, rework and a slipped schedule. Yet most ERPs have no real home for drawing revisions or customer approvals, so this high-risk step ends up in email threads and shared folders. ARKcelerate puts the approval inside the system and makes the approved revision the gate that production and quality work to.
The problem: approvals live in email and folders
When approvals sit outside the ERP, nobody has a single answer to “which revision is approved, and is it the one on the floor?” Drawings get emailed back and forth, sign-offs live in someone’s inbox, and a late approval only becomes visible when the project is already behind. The ERP keeps planning and purchasing as if everything were settled, because it has no idea an approval is still outstanding.
How ARKcelerate handles drawing approvals
Every revision tracked through customer sign-off
Each drawing revision is logged and moved through customer approval inside the Customer Approvals module, with a full audit trail of who submitted what, when, and what the customer said. The approved revision becomes the single source of truth for that scope of work — visible to engineering, production and QC alike.

The approved revision drives the floor and QC
Production works to the approved revision, and quality inspects against that same revision — so “which version is correct?” is never a question on the shop floor. Because the approval, the manufacturing order and the QC inspection all reference one revision, you can prove exactly what was built and checked against what the customer signed off.
Overdue approvals raise tasks automatically
When a customer approval is overdue, ARKcelerate raises a task and notifies the right people automatically, so a stalled sign-off surfaces immediately instead of quietly holding up the project. The delay becomes a visible, owned action — not a surprise discovered at the production meeting.

Why it matters
The approval gate is where engineered-to-order risk concentrates: build to the wrong revision and the cost is immediate and physical. Keeping revisions, approvals and the resulting inspections on one thread protects both margin and schedule — and gives you a defensible record that production matched the approved drawing every time.
In ARKcelerate this lives in the Customer Approvals module, working hand in hand with Manufacturing and Quality, so the approved drawing flows straight into what gets built and how it is inspected.

Frequently asked questions
How does a customer drawing approval workflow work in ARKcelerate?
Each drawing revision is logged and routed through customer sign-off in the Customer Approvals module, with a full audit trail. The approved revision becomes the single source of truth that production builds to and quality inspects against.
Can production start before the drawing is approved?
The approved revision is what the shop floor works to, and the manufacturing order and QC inspection reference that same revision — so an unapproved or superseded drawing does not drive production.
What happens when a customer approval is overdue?
ARKcelerate raises a task and notifies the responsible people automatically, so an overdue approval surfaces as an owned action immediately rather than silently delaying the project.
Does quality inspect against the approved revision?
Yes. QC inspections are tied to the manufacturing order and the customer-approved drawing revision, so you can prove exactly what was checked against which approved specification.
Is this suitable for engineered-to-order and submittal-heavy manufacturers?
Yes — it is built for shops where each order needs customer-approved drawings before fabrication, including engineered-to-order, make-to-order and submittal-driven project manufacturing.
