Editing for Editors of Proofed

Proofed is a UK based company that offers quality proofreading services to students, professionals as well as business owners. They are the experts of their industry and are known to have served in more than 100 countries. Initially, the company used to work with students and offered the “Pay as you go” option. But they wanted to expand their services to businesses and organizations so that they can get bulk work and documents for proofreading. BiztechCS has helped Proofed expand their horizons and realize their business plans by being their technological partner throughout their journey.

  • Supports Multiple Payment Modules
  • CustomerIO
  • Xero Integration with Backend

Project highlights:


Background Processes:

The client wanted to change the format of the document from .doc to .docx which was not possible due to unexpected errors from Cloudflare services. Since this was something that could add positively to their customers’ experience, we found a way through this issue. To make the conversion, we decided to run processes like CLI (command line interface) in the background. Simultaneously, we also had to show these processes to the user in frontend. This task was a tad tricky since the processes run in its own particular thread.

Since we were processing requests in the backend, it became easier for the user to add new documents, services, navigate the website, and many such tasks. This also reduced Cloudflare timeout errors. Up to that, Xero Integration with the backend helped in tracking and managing orders and payments.

Enhancing customer experience:

There were multiple flows and API integrations that were causing some issues on the website making it difficult for users to use their services. To solve this problem, we decided to log data from websites for high-level processes like document upload and email alerts on critical processes like duplicate payment.

This made it easy for the client to identify any issue as they can just go through the log. This also made it easy to know the specific flow, resolve the issue, and know the exact data inputs which we get from the logs. Additionally, logs take up disk space on the server so it was essential for us to decide which data is important and whose logs we should be keeping. Additionally, admin can provide businesses with API, using which they can upload documents. This makes the upload process simple and easy to use.

API integrations

Global Payments made Easy

This website is available in different countries like AU, US, UK. To make their payments easy, we implemented a Stripe account so that users can pay in their national currency, securely. Customers can pay via three payment methods i.e. Credit/Debit card payment, AliPay, and WeChat. It is our aim to provide users with multiple payment modules so they can make payments easily without any hassle.

Global Payments

Simplified Admin Operations

Now admins can easily create organizations and set pricing as per the organization. So, users can login to the organization with provided emails. Admins can also show the organization’s logo and pricing according to configurations. Added super admin that can access all the modules. Under Super Admin, Admin can access main modules.

Previously, Admin was able to upload a single document at a time. We have added multiple document uploads in admin upload. So, Admin can upload multiple documents at a time. Added action log functionality to track admin activity. We have added this functionality for documents, users and freelancers. For example, when the user’s details are changed. We have added it in the action log and shown it to the user’s details page. In the new update, the admin can change the currency of customers as well as the organization. This helps customers to easily make a payment in the currency of their choice i.e USD, AUD, GBP.

Creative Feedback Display

Added a fixed number of usage functionality for offers. Here admin can offer a number of usages. For example, Admin adds a coupon 400 words free for the first 2 documents only. Then a user can use that coupon for 2 times only for the first 2 documents.

Logging and monitoring critical process

The website was using multiple processes, third party APIs, etc. which were making it difficult to understand how many services the website depended on. We decided to log the data of the third-party libraries, multiple APIs, sentry tool, etc. so it becomes easy to find issues, understand and then solve them. Documenting everything from the scratch was important for us as we needed to understand which flow depended on which API library.

Multiple document formats and their price calculation

The client wanted to support more than 10 file formats including PDF, LaTex, MS Powerpoint, Google Docs, Plain Text, etc. The complicated part was to get the word count for each format and calculate price per word and per page for each file format. Additionally, it also required proper integration with different APIs like Google Drive, Google OCR, Cloud Converter, and many more.

Other updates during our recent sprint:

  • Updating payment modules
  • Background running processes
  • Long-running processes
  • Resolving slack issues
