Remodeling Access existing systems

Modify the system you are currently using

Version upgrade of Access. (Example) I want you to upgrade from Access2000 to Access2021
Because the person in charge of production has quit, data errors are appearing and it is troublesome.
Currently, I am using it standalone, so I want it to be a specification that can be shared by multiple people.
Because it is produced in-house, the operability is poor, so I want it to be a good operability that anyone can use.
I want to add new features to our current system.

1. First, we will check the current system.: We will ask you about the contents of the remodeling and additional items.
2. Submit a quotation: We submit a quotation.; ( So far, we will respond free of charge. )
3. Orders: After receiving your order, we will confirm the specifications and delivery date.; Please pay approximately 20% of the order amount as a starting fee.
4. Design and specification determination: Retrofit Program Design; Checking Specifications
5. Programming
6. Test operation and operation confirmation: At this stage, the customer will be asked to confirm the operation once.; We will repeat the data entry test and the printing test within our company to confirm the movement.
7. Program fixes and tweaks: Fine-tune the specification.
8. Delivery and production: We will set up the PC or file server specified by the customer.
9. 3 months free support period: The free support period is usually 3 months.

Since it depends on the contents of the remodel, we will quote individually. A common case is around $15000 ~ $30000.
Changing the search screen, etc. is relatively easy, so the cost of remodeling is cheaper.
It is also easy to change printed forms, so it is cheap.
If you want to modify the structure of the table, which is the storage part of the data, it will affect the query, form, etc., so it will be relatively expensive.
